Magnet and Magnetic Fields

What is the magnetic attraction or repulsion of a magnet called?

• the magnetic domain

• the magnetic field

• the magnetic pole

• the magnetic force

Which type of magnet does not lose it's magnetic properties easily.

• a permanent magnet

• an electromagnet

• a temporary magnet

• a nail rubbed across the north pole of a magnet

The space in which the magnetic effects exists is called

• the magnetic field

• the magnetic equator

• the magnetic material

Paper clips and staples are attracted to magnets because paper clips and staples are

• permanent magnets

• temporary magnets

• magnetic materials

• magnetic domains

What are the two magnetic forces?

• attraction

• equilibrium

• magnetic acceleration

• repulsion

Magnetic field lines always cross.

• True
• False

Are the magnetic field lines in the picture correct?

• Yes, because they point from north to south.

• No, because they point from north to south (they're supposed to go the other way).

• Yes, because the North pole is on the left in all pictures.

• No, because the North pole is on the left in all pictures (it's supposed to be on the right).
